Tunnel dynamic feedback analysis system based on IFC standard

Abstract

The invention discloses a tunnel dynamic feedback analysis system based on an IFC standard, and the system comprises a BIM model library operation module for establishing a tunnel model, a model analysis module, a data reading module, an analysis report module, and a surrounding rock classification module. The BIM model library operation module is used for creating a typical tunnel model and a parameterized component library and exporting the typical tunnel model into an IFC format file to form an IFC model; the model analysis module, the surrounding rock classification module and the analysis report module obtain surrounding rock dynamic classification and surrounding rock identification parameters through extracting the IFC format file related attribute data and performing calculation, and generate a report form; a feedback analysis calculation program is called to obtain an excavation construction scheme and support parameters, the data reading module writes dynamical classification of the surrounding rock and the surrounding rock identification parameters into the IFC model. According to the invention, comprehensive rapid analysis and accurate processing of various data and information are ensured, feedback analysis is carried out on the data, and accurate presentation of the data is realized.

Description

technical field [0001] The invention relates to the technical field of BIM, in particular to an IFC standard-based tunnel dynamic feedback analysis system. Background technique [0002] The geological conditions of underground geotechnical engineering such as tunnels and foundation pits are complex and changeable. Existing technologies cannot accurately grasp the properties of rock and soil. Traditional analysis and numerical calculations often have large differences between model parameters and actual conditions, and human experience is also blind. Therefore, modern tunnel construction concepts represented by "new Austrian method construction" and "observation method construction" pay special attention to the feedback analysis of construction process information. With the development of geotechnical engineering informatization and computer technology, many 2D data processing software and 3D modeling and visual analysis systems have come out one after another, but most of th...

Problems solved by technology

With the development of geotechnical engineering informatization and computer technology, many 2D data processing software and 3D modeling and visual analysis systems have come out one after another, but most of these software systems are aimed at a certain professional field or only provide visual display of the model, lacking unity Due to the constraints of data standards, various engineering data exist in isolation in their own systems, and it is impossible to realize the data interaction of various analysis software

In actual engineering applications, it often presents the characteristics of low efficiency of information management and utilization, one-sided means of information sharing, and poor inter-disciplinary communication of information, which cannot meet the needs of geotechnical engineering construction.
